WireShark-Introduction: WireShark is an open source network packet capture, display and analysis tool that runs in many versions of Linux, UNIX, and Windows.  It can be used to achieve many positive outcomes, including: troubleshooting network problems, examining security problems, debug protocol implementations and learn internal details and functioning of network protocols.  It also can be used for nefarious purposes that breach the confidentiality of network data exchanges by observing the users as they interact with systems within intranets and across wide-area networks. Confidentiality breaches include: extracting usernames and passwords; identifying data stores, servers, services and applications, and determining how users access and use them directly and indirectly them through browser based screens, pages, applications and services.

WireShark-Using: This reading introduces how Wireshark works, including how to capture, view, filter, and analyze data packets exchanged over an IT network via a number of different computer, telephony, internet, and web data interchange protocols.
